To all whom it may concern: y

Be it known that I, Cnnluns E. FOSTER, a citizen of the United States,and a resident ofWashington, District of Columbia, have invented certainnew and useful Improve# ments in Duplicating Devices for Type'- Writers,of which the following is a specifil cation.

My invention relates to typewriting machines and has for itsobject toavoid the necessity of the use of separate duplicating y carbon sheetsin printing duplicates, and more especially to avoid the delay andmanipulation required for the use of such sheets in duplicating billsupon folded sheets, and to this end my invention consists of a rollsupporting a duplicating strip, with means whereby the latter can bebrought in proper relation to the sheets to be printed, and with l meansfor automatically turning the roll when draft upon the duplicating stripis released, las fully set forth hereinafter and as illustrated in theaccompanying drawing, in which:

Figure 1 is a transverse section of sufficient of a Remingtontypewriter' to illustrate the application of my invention in connectiontherewith; and .with the use of separate original and dir licatingsheets; Fig. 2 is a face view of the evice as adapted for at taclnnentto the Remington typewriter; Fig. 3 is a perspective view illustratinglanother form of a device especially adapted for use in connection withfolded billing sheets; Fig. l is an edge view of the device shown inFig. 3; Fig. 5 is a b'ack view of part of the device; Fig. 6 is atransverse sec tional elevation showing the device in a somewhatdifferent form as applied to a Monarch machine; Fig. 7 a back viewsupported by a frame D supported in any suitablemanner, referablydetachabl ,upon the carriage, an with the roller C 1s oombined a springS or weight, or other means whereby, when the duplicating sheet is drawnaway from the roller, it will be rewound thereon by the power of saidspring or Weight. For many purposes an ordinary spring curtain rollermay be em loyed, the Hattened end of the non-rotatale spindle 1 of thesaid roller fitting a slot :c in one of the upturned ends 2 of the frameD. Against the platen B bears the presser roll 16 and the roll 4ccarried by the rocking frame E, which is swung in one direction by aspring 5 and which can be rocked to carry the pressure roll away fromthe platen by means of an arm 6.

As shown in Figs. 1 and 2, the duplicating devices are supported uponthe usual detachable plate F of the typewriter, which is of theRemington type.

The parts are so adjusted that when the roller is wound up to thegreatest'extent, there will be a free end or part of the-sheet Vextending from the roll to a position near the platen and adapted to begrasped at one or both edges by the operator, and as the sheet V isnarrower than the platen, and wider than the plate'F, which may be cutaway at the sides, the usual bill sheet or original sheet X may bepassed above the plate F and beneath the strip V, while the duplicatingsheet Y is placed above the strip V in the position shown in Fig. 1,when the operator, by pinching the side portions of the sheets together,can pass them downward between the rolls B and 4, until properlygrasped, and then by turning the platen roller B by the usual knob, thesheets are carried together into position for the original sheet X to beprinted, while at the same time the duplicate will be produced.

After-the printing is effected, the roller B may be turned back untilthe lower edges of the sheets X and Y pass from between the platen andthe roll'4, when they can be readily detached, the spring of the rollerC causing the strip or duplicating sheet V to be wound up and carried toits original position, leaving the end c/ in position to be grasped, orthe rolls 4 and 16 can be moved away from the platen when the roll Cwill ror o Va frame` having a light fabric u stretched over it, as shownin Fig. 6, or of open-work material to reduceweight, and is o such sizeas to ermit the folded sheet or separate sheets to placed upon' itlaterally with one part or sheet below vand the other above the strip V,the roller C in -this case and upward to an eye 10 upon the beingsupported at the top of the frame and having a reduced drum 7 at oneend, around which is wound a cord 8, the latter passing downward beneatha pulley 9 of a weight W lrame, with the result that when the strip V isdrawn upon, the weight will be raised, and will turn the roller and windup the strip v when draft upon the latter is released.`

In order to properly position each folded sheet in respect to theplaten, especially when it is necessary to print at successive timesupon the saine folded sheet, and therefore desirable that it should oneach occasion occupy the saine position as before in respect to theplaten, I provide a guide G snitably arranged between tlie platen andthe roller, whereby when olie part of the folded sheet is passed beneaththe Guide and above the strip, until the folded until grasped by thesame, when the print.

ing maybe done as usual. lAfter the desired printing is effected, theremoval of the printed 'slieet or sheets may be effected.

The device in Fig. 6 is shown in connecttion with a machine like theMonarch,

where there are two presser rolls 4 and 16, both of which may be carriedfrom the platen by the operation of a lever 6. In

`the construction shown in Fig. 6, the weight hangs directly fiom thecord without the intervention of the pulley 9 as in Fig. 3, but iii eachease a suitable guide rod 12 at the rear of the frame may pass throughthe weight o i through an eye 13 on the weight and guide the latter andprevent it from swinging.

the use of a weight as described, the tension tending to turn the rolland lift the sheets etdge of the sheet,l bears against the edge of theguide, the

sheet is uniform, while in the case of a spring it will increase as thespring is wound up, but this latter result may be revented forming thedrumwith a gra ually increasing spiral groove 15, as shown in Fig. 8.

In Fig. 7 th plate carries at the rear a drum H in which is a sprin 20tending to turn the drum so as to win up the cord 8 and turn the rollerC.

, In order to properly connect the vstrip Vl to the roller C, the lattermay have a lon tudinal groove 1'?, Fig. 9, above which t e end of thesheet may be placed, a strip or rod 18 being then forced inward so as todouble the strip around it and secure it to the roll.

It will be'evident that the frame or plate between the roll and theplaten may be vertical or horizaiital or inclined, as may be desired,and that the plate serves as a snpport for the strip of duplicatingmaterial, holding it in position to permit the paper sheets to b'eproperly applied and preventin tearing and injury. It will further benote that the free end portion of the duplicating strip is normally sodisposed on the supporting plate that not only the side edge por.

tions but the lower end or edge ortion of the said stri can bemanipulate lso that a bill sheet folded along its to ed e may be appliedtop downward to tie uplicatiiig strip so that the strip will be embracedbetween the folds of the bill sheet and the end of the strip will liewithin the horizontal biglit or fold of the bill sheet.

Without limiting myself to the precise construction and arrangement ofparts herciii shown, I claim:

1. The combination with a carriage and platen ofia t pewriting machine,of a roll iaving a dup icating strip Wound thereon, a support arrangedto hold said roll above the carriage to normally resent a portion of thestrip between the roll)and the carriage with the side edges and loweredge exposed to be manipulated, and means for turning the roll to rewindthereon any part of the strip dravsfn from the roll. f

2. The combinationwith acarriage, platen and presser rolls of a tpewriting machine, of a roll having a uplicating stris wound thereon, a4support arranged to hol Cri the roll above the carriage to normallypre- @Het lloose or free end of the strip being left platen and presserrolls of a typewritingmachine, oa roll supported on the carriage andhaving#A -a duplicating strip Wound thereon, to normally leave a looseend enn tending between the roll and the platen in position to permitthe lower edge andv side ed e portions to be grasped between the rol andthe platen, and means for moving the presser rolls toward and away fromthe platen.

6'. ln a typewriting machine, the combi i nation of a rotary ,materialcarrying device capable of a" lurality of complete rotations to unwind te material, means operative automatically to turn said device through aplurality of complete rotations to rewind a vstantially to the portionof the material, and for controllin the parts so that the portion ofthemateria revvound on said device shall' be equal sub- (portion previouslyun- Wound, all arrange to expose 4the material below the carrying deviceso that the lower.

edge and the side edge portions of said material may be caused tocoperate with a bill sheet havingV a horizontal folded edge.

7. In a typevvriting machine, the combination of a holder 'for a roll ofcarbon paper, pa r feeding devices adapted to feed to nfet er the carbonpaper from said roll holder and-the paper to be Written upon, a

,ete i supporafor the paper and the carbon sheets between the platen andthe roll, means for means for rewinding on said roll holder the portionof the carbon paper that has been unwound from said roll holder'by thepaper feedin devices, all arranged to expose the paper eloW theholder'so that the bottom edge and side edge portions of the paper maybe brought into coperation With .a Work sheet having a horizontal foldeded e.

8. ln a typewriting machine, the com ination of a carriage, a rotaryroll holder arranged above the carriage, an axle therefor, a sp1-ingconnected with said rroll holder, paper feeding devices o erative todraw the material from Said rol holder, the tension of said spring beingthereby increased, and

a lixed relationship with its bearings, the roll holder 'being arrangedto sup ort the '.'l'ree end of the pa er exposed4 belldw said rollholder so that t e bottom and side edge portions of said paper may befree and accessible.

nation of a carriage, a platen, a roll carrying a' duplicating stri andmeans for turning the roll`to 'reWin the strip thereon, all arran ed tolexpose a art of the stri above so that. the side edges and bottom edgeof thev strip are free and accessible and occupy a positlon-between theroll and the platen when the roll is in normal position. ln testimonywhereof I aflix my signature in presence or two Witnesses.'
